Gaphas: While re-sizing a child state size extends in opposite direction if mouse on boundary of parent state

[franzlst]

If child states are re-sized and the mouse moves on the parent boundaries the child extends in the opposite direction. I talked to @sebastian-brunner and he also thinks that is buggy behavior.

Procedure:

• create a new state machine
• add a new state
• re-size the new child state till you reach the boundary (like on the right side) of the parent (so the child state is extending to the left)

I could estimate that the shrinking after moving with clicked mouse to the left again is an appropriate behavior but the extending only easily can be embarrassing if only accidentally touching the parent boundary. The shrinking or no extending of the state both could be a solution to the current behavior. Maybe we discuss it.

Finally this issue needs a representation (test) in issue #175 to preserve gaphas functionality and as reliability to the user.
